 Calc is an interactive calculator which provides for easy large
 numeric calculations, but which also can be easily programmed for
 difficult or long calculations.  It can accept a command line
 argument, in which case it executes that single command and exits.
 Otherwise, it enters interactive mode.  There are a great number
 of pre-defined functions.  The calculator can calculate transcendental
 functions, and accept and display numbers in real or exponential format.
 The calculator also knows about complex numbers.
